Description:

FIELD OF THE INVENTION

[0001] The present invention relates to the technical field of
communication, and in particular to an apparatus and method for
implementing mass texting.

BACKGROUND OF THE INVENTION

[0002] In an Android mobile phone with single chip and dual Central
Processing Unit (CPU) architecture, the shared memory of communication
CPU and application CPU is limited. All the information of dual CPU
communication needs to pass through this shared memory. Therefore, the
storage space left for short messages in the shared memory is very
limited and it is generally a storage space for dozens of short messages.
Thus, when dozens of short messages are sent at one time, and especially
when hundreds of short messages are sent, the communication CPU will be
blocked and causes the mass texting performance to be unstable, with slow
speed, and easy to be lost.

[0003] In the related art, in order to prevent the communication CPU being
blocked when sending short messages massively, a method of increasing
short message storage space can be used. However, this will cause the
storage space used for other services to be reduced significantly and it
would be disadvantageous for the timely and rapid process of other
services.

massively to the sending unlock module, requesting the sending unlock
module to forward this short message to the communication CPU, and after
the sending unlock module forwards this short message to the
communication CPU, locking the short message sending thread by starting
the synchronization lock, and waiting for unlock.

[0011] Furthermore, the sending unlock module is further configured for
forwarding this short message to the communication CPU according to the
request of the sending lock module, and judging whether a acknowledgement
of receipt of this short message returned by the communication CPU is
received within a predetermined time: if yes, then unlocking the
synchronization lock and triggering the sending lock module to continue
to send a next short message; otherwise, unlocking the synchronization
lock, setting that the short message is sent unsuccessfully, triggering
the sending lock module to continue to send a next short message, and
triggering the sending lock module to resend this short message which is
sent unsuccessfully after other short messages to be sent are all sent.

[0012] The present invention further provides a method for implementing
mass texting which employs an apparatus for implementing mass texting,

module, and the method comprising:

[0013] Step A: the sending lock module sends one short message in the
short messages to be sent massively to the sending unlock module,
requests the sending unlock module to forward this short message to a
communication CPU, and locks a short message sending thread after the
sending unlock module forwards this short message to the communication
CPU;

[0014] Step B: the sending unlock module forwards this short message to
the communication CPU according to the request of the sending lock module
and unlocks the short message sending thread when receiving the
acknowledgement of receipt of this short message returned by the
communication CPU, and turn to step A to continue to send a next short
message; and repeatedly performing steps A and B till the short messages
to be sent massively are all sent.

[0015] Furthermore, a synchronization lock for locking short message
sending thread is preset, and the step A further includes the following:

[0016] the sending lock module sending one short message in the short
messages to be sent massively to the sending unlock module, requesting
the sending unlock module to forward this short message to a
communication CPU, and after the sending unlock module forwards this
short message to the communication CPU, locking the short message sending
thread by starting the synchronization lock and waiting for unlock.

[0017] Furthermore, the step B further includes the following:

[0018] the sending unlock module forwarding this short message to the

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0027] The preferred embodiments of the present invention will be
described in detail in conjunction with the drawings hereinafter. The
drawings constitute part of the present application and are used for
explaining the principles of the present invention together with the
embodiments of the present invention. For the sake of being clear and
concise, when it may cause the subject of the present invention to be
vague, the detailed and specific description of the already known
functions and structures of the devices described herein will be omitted.

[0028] The apparatus according to the embodiments of the present invention
will be first described in detail in conjunction with FIG. 1.

[0029] As shown in FIG. 1, FIG. 1 is a structural schematic diagram of an
apparatus according to the embodiments of the present invention. The
apparatus can comprises: a sending lock module and a sending unlock
module, wherein the function of the sending lock module can be realized
by the APP (application) module in the application CPU in the embodiments
of the present invention, and the function of the sending unlock module
can be realized by the RIL (Radio Interface Layer) module in the
application CPU in the embodiments of the present invention. The specific
implementation of the APP module and RIL module will be described in
detail below.

[0030] The APP module is mainly responsible for sending one short message
in a plurality of short messages to be sent to the RIL module, requesting
the RIL module to forward this short message to a communication CPU, and
locking a short message sending thread after the RIL module sends this
short message to the communication CPU. Specifically, a synchronization
lock for locking the short message sending thread is preset, and the APP
module sends one short message in a plurality of short messages to be
sent to the RIL module, requests the RIL module to forward this short
message to the communication CPU, and after the RIL module sends this
short message to the communication CPU, locks the short message sending
thread by starting the synchronization lock, and waits for unlock.

[0031] The RIL module forwards the short message sent by the APP module to
the communication CPU, and after having received an acknowledgement of
receipt of this short message returned by the communication CPU, unlocks
the short message sending thread and triggers the APP module to continue
to send a next short message. Specifically, the RIL module forwards the
short message sent by the APP module to the communication CPU and judges
whether the acknowledgement of receipt of this short message returned by
the communication CPU is received within a predetermined time: if yes,
then unlock the synchronization lock and trigger the APP module to
continue to send the next short message; otherwise, unlock the
synchronization lock, set that the sending of this short message is
failed, trigger the APP module to continue to send the next short
message, and trigger the sending lock module to resend this short message
after other short messages to be sent are all sent.

[0032] The APP module and RIL module repeatedly perform the above process
till the short messages to be sent are all sent.

[0033] The particular implementation of the above apparatus according to
the embodiments of the present invention will be described in detail in
the following description of the method and specifically refers to FIGS.
2 to 4, which will not be described here redundantly.

[0034] The method according to the embodiments of the present invention
will be described in detail in conjunction with FIGS. 2 to 4 hereinafter.

[0035] The method according to the embodiments of the present invention
mainly comprises: the sending lock module requesting the sending unlock
module to send a short message to the communication CPU and locks a short
message sending thread after the sending unlock module forwards this
short message to the communication CPU; and the sending unlock module
unlocks the short message sending thread when receiving an
acknowledgement of receipt of this short message returned by the
communication CPU, and triggers the sending lock module to continue to
send a next short message till the short messages to be sent are all
sent.

[0036] As compared to the apparatus according to the embodiments of the
present invention, the implementation of the APP module and RIL module is
also used as an example to illustrate the method according to the
embodiments of the present invention.

[0037]FIG. 2 is a sequence diagram of a method for mass texting according
to the embodiments of the present invention. As shown in FIG. 2, a
synchronization lock for locking a short message sending thread is set,
and it is assumed that there are M short messages to be sent massively
this time and they need to be sent to destination address 1, destination
address 2, . . . , and destination address M respectively. Specifically,
the method can comprise the following steps:

[0038] Step S201: the APP module in the communication CPU sends one short
message (destination address 1) in the short messages to be sent
massively to the RIL module in the communication CPU and requests the RIL
module to forward this short message (destination address 1) to the
communication CPU;

[0039] Step 202: the RIL module sends this short message (destination
address 1) to the communication CPU via remote calling, and then informs
the APP module; and the short message sending thread in the APP module
will start the synchronization lock and wait for unlock; at this moment,
the short message sending thread is in the blocked state;

[0040] Step 203: a message receiving thread in the RIL module receives a
message returned by the communication CPU within a predetermined time
(such as 5 s);

[0041] Step 204: the message receiving thread in the RIL module performs
decoding process to the returned message, and unlocks the synchronization
lock when confirming that this returned message is the acknowledgement of
receipt of this short message (destination address 1);

[0042] Step 205: after the RIL unlocks the synchronization lock, the APP
module continues to send a next short message (destination address 2) in
the short messages to be sent massively to the RIL module;

[0043] Step 206: the RIL module sends this short message (destination
address 2) to the communication CPU via remote calling, and then informs
the APP module; and the short message sending thread in the APP module
will start the synchronization lock and wait for unlock; at this moment,
the short message sending thread is in the blocked state;

[0044] Step 207: the message receiving thread in the RIL module receives
the message returned by the communication CPU within a predetermined
time;

[0045] Step 208: the message receiving thread in the RIL module performs
decoding process to the returned message, and unlocks the synchronization
lock when confirming that this returned message is the acknowledgement of
receipt of this short message (destination address 2); and

[0046] the above sending process is repeated till M short messages to be
sent massively are all sent.

[0047] The method according to the embodiments of the present invention is
described above from the perspective of mass texting sequence, and the
particular implementation of the method according to the embodiments of
the present invention will be described in detail hereinafter.

[0048]FIG. 3 is a schematic diagram of the flow of a method according to
the embodiments of the present invention. As shown in FIG. 3,
specifically the method can comprise the following steps:

[0049] Step 301: when the application CPU edits and adds the numbers of M
short messages to be sent massively, the APP module in the communication
CPU sends one short message in the short messages to be sent massively to
the RIL module in the communication CPU;

[0050] Step 302: the RIL module sends this received short message to the
communication CPU via remote calling and informs the APP module that this
short message has been sent to the communication CPU;

[0051] Step 303: after the APP module learns that this short message has
been sent to the communication CPU, the short message sending thread in
the APP module starts the synchronization lock to enable this short
message sending thread to be in the blocked state and waits for unlock;

[0052] Step 304: the message receiving thread in the RIL module performs
decoding process to the message received within a predetermined time, and
confirms that this message is the acknowledgement of this short message
returned by the communication CPU after judgment; and

[0053] Step 305: the synchronization lock is unlocked, and turn to step
301 to continue to send the next short message.

[0054]FIG. 4 is a schematic diagram of another flow of a method according
to the embodiments of the present invention. As shown in FIG. 4,
specifically the method can comprise the following steps:

[0055] Step 401: when the application CPU edits and adds the numbers of M
short messages to be sent massively, the APP module in the communication
CPU sends one short message to the RIL module in the communication CPU;

[0056] Step 402: it is judged that whether the number of the sent short
messages is less than M, and if yes, then perform step 403, otherwise, it
indicates that the mass texting is completed;

[0057] Step 403: the RIL module sends this received short message to the
communication CPU via remote calling and informs the APP module that this
short message has been sent to the communication CPU;

[0058] Step 404: after the APP module learns that this short message has
been sent to the communication CPU, the short message sending thread in
the APP module starts the synchronization lock to enable this short
message sending thread to be in the blocked state and waits for unlock;

[0059] Step 405: the message receiving thread in the RIL module performs
decoding process to the message received within a predetermined time; and
when it is confirmed that this message is not the acknowledgement of this
short message returned by the communication CPU after judgment, a timeout
process procedure is started, i.e., the synchronization lock is unlocked,
the state of this short message is set to be failed-to-sent, and turn to
step 401 to send the next short message; and

[0060] Step 406: when other short messages to be sent are all sent, the
resend procedure is started, i.e., this short message which is sent
unsuccessfully is resent.

[0061] In summary, the embodiments of the present invention provide an
apparatus and method for implementing mass texting, and the synchronous
transmission of each short message between the application CPU and
communication CPU is ensured by the synchronization mechanism of the
thread during mass texting. It prevents the communication CPU being
blocked caused by disorderly asynchronously sending. It realizes that
mobile phone users can be mass texting for one time, and the number of
telephone numbers of each mass texting can be unlimited. After each time
one short message is sent out, the short message sending thread will
start a synchronization lock and wait for unlock. In the message
receiving thread, if the receiving communication CPU has received and
sent the same normally, then the synchronization lock is unlocked. If no
acknowledgement that the communication CPU has received and sent the same
normally is received within a predetermined time, the synchronization
lock is also unlocked, and the corresponding short message is set as in a
non-sent state, and the resend procedure is started after other short
messages to be sent are all sent.

[0062] In conclusion, the embodiments of the present invention solve the
problem that the communication CPU is blocked and the short messages
cannot be sent out timely when a dual CPU architecture mobile phone sends
hundreds of short messages massively. Furthermore, the present invention
does not need to increase the shared memory, and the number of short
messages to be sent massively for one time can be unlimited and they can
be sent out stably just by improving the internal procedure of mass
texting.

[0063] What is described above is merely preferred implementation of the
present invention. However, the protection scope of the present invention
is not limited to this. Any changes or replacements in the disclosed
technical scope of the present invention which can be easily thought of
by those skilled in the art shall be covered in the protection scope of
the present invention. Accordingly, the protection scope of the present
invention should be subject to the protection scope of the claims.
